Description

Pierce Protein Concentrators PES can be used for processing sample volumes up to 0.5mL and are available in four distinct molecular-weight cutoffs (MWCOs) of 3K, 10K, 30K and 100K. For easy identification, the MWCO value is etched on the side of each device. To assist with sample addition and recovery, a clear window with graduations is located on the side of each device enabling visual determination of the retentate volume. The vertical design of the membrane allows high flux rates, low non-specific binding and negligible protein aggregation on the membrane and provides reliable and consistent results for processing sample volumes between 100 and 500μL. Typical protein recovery is 90% when the mass of the proteins in the sample is at least two-fold greater than the MWCO of the device used. Sample concentration of 10- to 30-fold can be achieved within 10 minutes. The 0.5mL Pierce Concentrators, PES are compatible with most bench-top microcentrifuges with fixed-angle rotors that accommodate 2.2mL tubes.

Highlights:

Rapid protein concentration – sample concentration of 10- to 30-fold can be achieved in 10 minutes or less
